Abstract
The ordered structures of two-species ions stored in a Paul trap are simulated by minimizing the total effective potential energy of the ion system. It is shown that the homo-charged two-species ion clusters display separating and mixing structures for different mass and charge ratios. The hetero-charged ion clusters consisting of one light negatively (positively) charged ion and three to six heavy positively (negatively) ions are found to exist stably, and the stability conditions obtained through the perturbative analysis indicate that the ion cluster consisting of more heavy ions has a looser limitation on mass and charge ratios of two-species ions.
